这个整个表格数据都是后台返回的,并不是合并表格的那种,所以需要手动对表格进行样式处理!

<el-table 
:data="tableData" 
border 
height="calc(400px - 0.52rem)" 
max-height="calc(400px - 0.52rem)" 
:row-class-name="TableRowClassName" 
:cell-style="tableRowStyleName">
     <el-table-column prop="orgName" label="单位名称"></el-table-column>
     <el-table-column prop="loadCapacityUnit" label="载量检测单位"></el-table-column>
     <el-table-column
         v-for="(item, index) in tableOption"
         :key="index"
         :prop="item.sampleCode"
         :label="item.sampleCode">
     </el-table-column>
     <el-table-column prop="totalScore" label="得分"></el-table-column>
     <el-table-column label="预览"></el-table-column>
</el-table>

// methods里面的方法
TableRowClassName({row, rowIndex}) {
    // 最后两行固定
    if (rowIndex + 1 === this.tableData.length - 1) {
       return `tr-fixed fixed-row1`;
    } else if (rowIndex + 1 === this.tableData.length) {
       return `tr-fixed fixed-row`;
    } else {
      return ``;
    }
},
tableRowStyleName({row, rowIndex}) {
   if (rowIndex == this.tableData.length - 2 || rowIndex == this.tableData.length - 1) {
      return 'background-color: #E0E0E0 !important';
    }
}

<style lang="scss" scoped>

/deep/ .el-table {
    .tr-fixed{
        display: table-row;
        position: sticky;
        bottom: 0;
        width: 100%;
    }
    .fixed-row{
        bottom: 0;
    }
    .fixed-row1{
        bottom: 1.25rem; // 这里需要根据情况,自行稍微调整
    }
}

</style>

以下是固定三行:

// methods里面的方法
TableRowClassName({row, rowIndex}) {
     // 最后三行固定
     if (rowIndex + 1 === this.tableData.length - 2) {
         return `tr-fixed fixed-row2`;
     } else if (rowIndex + 1 === this.tableData.length - 1) {
         return `tr-fixed fixed-row1`;
     } else if (rowIndex + 1 === this.tableData.length) {
         return `tr-fixed fixed-row`;
     } else {
         return ``;
     }
}

<style lang="scss" scoped>

/deep/ .el-table {
    .tr-fixed{
        display: table-row;
        position: sticky;
        bottom: 0;
        width: 100%;
    }
    .fixed-row{
        bottom: 0;
    }
    .fixed-row1{
        bottom: 1.25rem; // 这里需要根据情况,自行稍微调整
    }
    .fixed-row2{
        bottom: 2.5rem; // 这里需要根据情况,自行稍微调整
    }
}

</style>
